2. Description of the Related Art

Wireless communication devices, such as cell phones, typically include antennas for transmitting and receiving radio frequency (RF) signals. In recent years, with the continuous development of mobile communication and the pressing demand for high data rate and stable communication quality, relatively high frequency wireless transmission (e.g., 28 GHz or 60 GHz) has become one of the most important topics in the mobile communication industry.

In a comparative wireless communication device, antennas and circuits (e.g., radio reference (RF) circuits or digital circuits) are disposed on a printed circuit board (PCB) or a substrate. However, it is difficult to fine turn the antennas. In addition, the entire wireless communication device fails if one of the antennas or the circuits fails, which would reduce the yield rate for manufacturing the wireless communication device.

DETAILED DESCRIPTION

FIG. 1 illustrates a cross-sectional view of an antenna module 1 in accordance with some embodiments of the present disclosure. The antenna module 1 includes an antenna layer 10, a package body 11 (also can be referred to as a “support”), a conductive pillar 12 and an electrical contact 13.

The antenna layer 10 includes an antenna pattern 10 c and a dielectric layer 10 d. A portion of the antenna pattern 10 c is covered or encapsulated by the dielectric layer 10 d and the other portion of the antenna pattern 10 c is exposed from the dielectric layer 10 d. For example, the antenna layer 10 (or the dielectric layer 10 d) has a surface 101 and a surface 102 opposite to the surface 101, and a portion of the antenna pattern 10 c is exposed from the surface 101 and the surface 102 of the antenna layer 10 (or the dielectric layer 10 d).

In some embodiments, the antenna pattern 10 c is, or includes, a conductive material such as a metal or metal alloy. Examples of the conductive material include gold (Au), silver (Ag), aluminum (Al), copper (Cu), or an alloy thereof. In some embodiments, the antenna pattern 10 c may include a single antenna element. In some embodiments, the antenna pattern 10 c may include multiple antenna elements. For example, the antenna pattern 10 c may include an M×N array of antenna elements, where M or N is an integer greater than 1. In some embodiments, M can be the same as or different from N depending on design specifications. In some embodiments, the antenna pattern 10 c may be a patch antenna, a dipole antenna, a horn antenna, a loop antenna, a planar inverted F antenna (PIFA) or any other antennas.

In some embodiments, the antenna pattern 10 c includes a plurality of conductive layers. A width of each conductive layer of the antenna pattern 10 c is less than 20 micrometer (μm). For example, the width of each conductive layer of the antenna pattern 10 c is less than 10 μm. For example, the width of each conductive layer of the antenna pattern 10 c is less than 5 μm. For example, the width of each conductive layer of the antenna pattern 10 c is equal to or less than 2 μm. In some embodiments, a distance between two adjacent conductive layers is less than 20 μm. For example, the distance between two adjacent conductive layers is less than 10 μm. For example, the distance between two adjacent conductive layers is less than 5 μm. For example, the distance between two adjacent conductive layers is equal to or less than 2 μm. In some embodiments, a tolerance of the width of the conductive layers of the antenna pattern 10 c is less than 3 μm. For example, the tolerance of the width of the conductive layers of the antenna pattern 10 c is less than 1 μm. For example, the tolerance of the width of the conductive layers of the antenna pattern 10 c is equal to or less than 0.5 μm.

In some embodiments, the dielectric layer 10 d may include molding compounds, pre-impregnated composite fibers (e.g., pre-preg), Borophosphosilicate Glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, Undoped Silicate Glass (USG), any combination thereof, or the like. Examples of molding compounds may include, but are not limited to, an epoxy resin including fillers dispersed therein. Examples of a pre-preg may include, but are not limited to, a multi-layer structure formed by stacking or laminating a number of pre-impregnated materials/sheets. In some embodiments, there may be a plurality of dielectric layers arranged in a stacked structure, and the number of the dielectric layers can be adjusted or changed depending on different design specifications. In some embodiments, the dielectric layer 10 d may include a photosensitive material, such as polyimide (PI).

The conductive pillar 12 (e.g., Cu pillar) is disposed on the surface 102 of the antenna layer 10 and electrically connected to the antenna pattern 10 c exposed from the dielectric layer 10 d. In some embodiments, the conductive pillar 12 is electrically connected to a feeding point of the antenna pattern 10 c for signal transmission between the antenna layer 10 and other electronic components (e.g., RF circuits, passive elements or circuit boards). In some embodiments, the number of the conductive pillar 12 can be adjusted depending on different design specifications. In some embodiments,

The package body 11 is disposed on the surface 102 of the antenna layer 10. The package body 11 covers a portion of the conductive pillar 12 and exposes the other portion of the conductive pillar 12 for electrical connections. For example, a surface 122 of the conductive pillar 12 is exposed from a surface 112 the package body 11. For example, the surface 122 of the conductive pillar 12 is substantially coplanar with the surface 112 of the package body 11. The electrical contact 13 (e.g., a solder ball) is disposed on the surface 122 of the conductive pillar 11 exposed from the package body 11. The package body 11 includes a material having a relatively low dielectric constant. In some embodiments, the package body 11 includes an epoxy resin having fillers, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material with a silicone dispersed therein, or a combination thereof.

In some embodiments, the package body 11 and the dielectric layer 10 d of the antenna layer 10 are formed of different materials. In some embodiments, a thickness of the package body 11 is different from a thickness of the dielectric layer 10 d. For example, the thickness of the package body 11 is greater than the thickness of the dielectric layer 10 d. For example, the thickness of the package body 11 is equal to or greater than 100 μm (e.g., 200 μm). For example, the thickness of the dielectric layer 10 d is equal to or less than 50 μm (e.g., 20 μm).

FIG. 2 illustrates a cross-sectional view of a semiconductor device package 2 in accordance with some embodiments of the present disclosure. The semiconductor device package 2 includes a substrate 20, the antenna module 1 as shown in FIG. 1 , an electronic component 21, a package body 22 and an electrical contact 23. In some embodiments, the semiconductor device package 2 may be a wireless communication device or parts of a wireless communication device.

The substrate 20 may be, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The substrate 20 may include an interconnection structure (or electrical connection), such as a redistribution layer (RDL) or a grounding element. The substrate 20 has a surface 201 and a surface 202 opposite to the surface 201. The substrate 20 may include one or more conductive pads 20 c in proximity to, adjacent to, or embedded in and exposed at the surfaces 201 and 202 of the substrate 20. The substrate 20 may include a solder resist (not shown in FIG. 2 ) on the surface 201 and/or 202 of the substrate 20 to fully expose or to expose at least a portion of the conductive pads 20 c for electrical connections. For example, the solder resist may cover a portion of the conductive pads 20 c.

The antenna module 1 is disposed on the surface 201 of the substrate 20 and electrically connected to the conductive pads 20 c of the substrate 20 through the electrical contact 13. The package body 11 of the antenna module 1 is disposed between the antenna layer 10 of the antenna module 1 and the substrate 20. For example, the antenna layer 10 is closer to the surface of the package body 11 facing away from the substrate 20 than the surface 112 of the package body 11. The surface 112 of the package body 11 of the antenna module 1 faces the surface 201 of the substrate 20 and spaced apart from the surface 201 of the substrate 20. For example, there is a gap (e.g., air gap) between the surface 112 of the package body 11 and the surface 201 of the substrate 20. In some embodiments, the number of the antenna modules 1 can be changed depending on different design specifications. For example, there may be an M×N array of antenna modules 1 disposed on the surface 201 of the substrate, where M or N is an integer greater than 1.

The electronic component 21 is disposed on the surface 202 of the substrate 20 and electrically connected to the conductive pads 20 c of the substrate 20. The electronic component 21 may be a chip or a die including a semiconductor substrate, one or more integrated circuit devices and one or more overlying interconnection structures therein. The integrated circuit devices may include active devices such as transistors and/or passive devices such resistors, capacitors, inductors, or a combination thereof. For example, the electronic component 21 may include a RF circuit, a digital circuit and/or a mixed-signal circuit. In some embodiments, the number or the type of the electronic components 21 can be changed depending on different design specifications.

The electrical contact 23 (e.g. a solder ball) is disposed on the surface 202 of the substrate and electrically connected to the conductive pads 20 c. The electrical contact 23 can provide electrical connections between the semiconductor device package 2 and external components (e.g. external circuits or circuit boards). In some embodiments, the electrical contact 23 includes a controlled collapse chip connection (C4) bump, a ball grid array (BGA) or a land grid array (LGA).

The package body 22 is disposed on the surface 202 of the substrate 20. The package body 22 covers the electronic component 21 and a portion of the electrical contact 23. The other portion of the electrical contact 23 is exposed from the package body 22 (e.g., exposed from the surface Paragraph 2 of Article 22 of the Patent Act of the package body 22) for electrical connections. In some embodiments, the package body 22 includes an epoxy resin having fillers, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material with a silicone dispersed therein, or a combination thereof.

A conductive layer 10 a is disposed on the surface 101 of the substrate 10. In some embodiments, the conductive layer 10 a is formed of or includes gold (Au), silver (Ag), aluminum (Al), copper (Cu), or an alloy thereof. In some embodiments, the conductive layer 10 a acts as a ground layer or a RF layer for the antenna pattern 12, 13 or 14. An isolation layer 10 b (e.g., solder mask or solder resist) is disposed on the surface 101 of the substrate 10 to protect the conductive layer 10 a.

In some comparative wireless communication devices, RF and digital circuits are disposed on a PCB or a substrate, and antenna patterns are formed on the PCB or the substrate. However, if the performance of the antenna patterns cannot achieve the desired specifications, it is difficult to adjust (fine-tune) the performance of the antenna patterns. In addition, the entire wireless communication device would be determined to be failure, even if one of the antennas or the circuits fails, which would reduce the yield rate for manufacturing the wireless communication device. In accordance with the embodiments as shown in FIG. 2 , the antenna module 1 is a separated module, and the performance of the antenna module 1 can be adjusted (fine-tune) flexibly without affecting the electronic component 21 or the substrate 20. In addition, if one of the antenna module 1 or the electronic component 21 has a defect, they can be changed or substituted individually. This can increase the yield rate for manufacturing the wireless communication device.

In some embodiments, the antenna module 1 can be replaced by a substrate antenna (e.g., an antenna pattern formed on a substrate by a substrate built-up process), which can also increase the flexibility for designing the wireless communication device compared with the comparative wireless communication devices. However, the width, pitch and roughness of the antenna pattern of the substrate antenna are relatively large, which would adversely affect the performance of the substrate antenna. In the embodiments as shown in FIG. 1 , since the antenna module 1 may be formed by a wafer-level redistribution layer (RDL) process (which will be described in the following paragraphs), the width, pitch and roughness of the antenna pattern 10 c of the antenna module 1 are relatively small, which would improve the performance of the antenna module 1. For example, in the case that both the package body 11 of the antenna module 1 and the substrate antenna have a same thickness (e.g., 100 μm) and is operating in a same frequency (e.g., 77 GHz), the antenna module 1 and the substrate antenna may have similar gain, but the antenna module 1 can have a bandwidth (e.g., 2.4 GHz-3 GHz) broader than the bandwidth (e.g., 2 GHz) of the substrate antenna.

In addition, due to process constraint, the antenna pattern of the substrate antenna has a relative larger variation or tolerance compared with the antenna pattern 10 c of the antenna module 1. For example, the antenna pattern of the substrate antenna may have the tolerance of about 110 μm while the antenna pattern 10 c of the antenna module 1 has the tolerance less than 25 μm. Hence, compared with the substrate antenna, the antenna module 1 may have a smaller conductive pad to connect to a via, which would reduce the area of the antenna module 1.

Furthermore, the thickness of the package body 11 of the antenna module 1 can be changed or adjusted to control the performance of the antenna module 1. Compared with the substrate antenna, which should change its thickness by replacing the substrate with another substrate, it is easier to change the thickness of the package body 11 (e.g., may be performed by grinding). This would increase the flexibility to design the antenna module 1 to meet the desired specification.

FIG. 3 illustrates a cross-sectional view of a semiconductor device package 3 in accordance with some embodiments of the present disclosure. The semiconductor device package 3 is similar to the semiconductor device package 2 in FIG. 2 except that in FIG. 3 , the antenna module 1 is replaced by an antenna module 1′. The antenna module 1′ is similar to the antenna module 1 in FIG. 1 , and the differences therebetween are described below.

The antenna module 1′ comprises a circuit layer disposed on the surface 112 of the package body 11. The circuit layer includes a dielectric layer 30 d, a conductive layer 30 c and an under bump metallurgy (UBM) layer 30 u (which may include a plurality of conductive pads surrounded by the dielectric layer 30 d). In some embodiments, at least one of the conductive pads is electrically connected to the conductive layer 30 c. The dielectric layer 30 d is disposed on the surface 112 of the package body 11. The dielectric layer 30 d has an opening to expose the surface 122 of the conductive pillar 12. In some embodiments, the dielectric layer 30 d is similar to the dielectric layer 10 d, and the properties of the dielectric layer 10 d can be applicable to the dielectric layer 30 d. the UBM layer 30 u is disposed on a surface 30 d 2 of the dielectric layer 30 d and extends within the opening of the dielectric layer 30 d to be in contact with the surface 122 of the conductive pillar 12. The electrical contact 13 is disposed on the UBM layer 30 u, and electrically connects the antenna module 1′ to the substrate 20.

The conductive layer 30 c is disposed on the surface 30 d 2 of the dielectric layer 30 d. In some embodiments, the conductive layer 30 c may act as a ground layer for the antenna layer 10, and the signal transmission for the antenna layer 10 can be achieved by the conductive pillar 12. In the case that the conductive layer 30 c is connected to ground, the conductive layer 30 c can act as a shielding layer to prevent the electromagnetic interference (EMI) between the antenna module 1′ and the electronic component 21. In some embodiments, the conductive layer 30 c may act as a RF layer, which is magnetically coupled to the antenna layer 10 for signal transmission. In such embodiments, the conductive pillar 12 may be omitted or remain depending on different design specifications. The conductive layer 30 c may be electrically connected to the conductive pads of the FIG. 4 illustrates a cross-sectional view of a semiconductor device package 4 in accordance with some embodiments of the present disclosure. The semiconductor device package 4 is similar to the semiconductor device package 2 in FIG. 2 , and the differences therebetween are described below.

In FIG. 4 , the antenna module 1 is replaced by an antenna module 1″. The antenna module 1″ is similar to the antenna module 1 in FIG. 1 , except that the antenna module 1″ solely includes one conductive pillar 12 connected to the feeding point of the antenna layer for signal transmission. The semiconductor device package 4 further includes a conductive layer 40 disposed on the surface 201 of the substrate 20 and spaced apart from the antenna module 1″. The conductive layer 40 may have an antenna pattern including a first portion and a second portion, wherein the first portion is magnetically coupled to the antenna layer 10 for signal transmission and the second portion is grounded. In some embodiment, the conductive layer 40 may be a slot antenna.

To achieve a high performance of the coupling between the antenna layer 10 and the conductive layer 40, an alignment between the antenna pattern 10 c of the antenna layer 10 and the conductive layer 40 is a critical issue. In a substrate antenna, since the tolerance of the width and pitch of the antenna pattern is relatively large, it is difficult to achieve alignment between two antenna patterns. As mentioned above, the tolerance of the width and pitch of the antenna pattern 10 c of the antenna module 1 (or antenna module 1″) is relatively small. It is easier to align the antenna pattern 10 c of the antenna module 1″ with the conductive layer 40, which would further improve the performance of the semiconductor device package 4.

In some embodiments, the dielectric layers 10 d 1, 10 d 2 and 10 d 3 are collectively referred to as the dielectric layer 10 d. In some embodiments, the conductive layers 10 c 1 and 10 c 2 are connected to define the antenna pattern 10 c.

The package body 11 may be formed by molding techniques, such as transfer molding, compression molding or any other suitable processes.

In other embodiments, the method in FIG. 6A, FIG. 6B and FIG. 6C can be used to manufacture other antenna modules. In some embodiments, the operation in FIG. 6A is performed subsequent to the operation in FIG. 5E.

Referring to FIG. 6C, an electrical contact 13 is formed on the UBM layer 30 u. The carrier 59 is then removed to form the antenna module 1′ as shown in FIG. 3 .

As used herein, the terms “substantially,” “substantial,” “approximately,” and “about” are used to denote and account for small variations. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation of less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%.

The term “substantially coplanar” can refer to two surfaces within micrometers of lying along a same plane, such as within 40 μm, within 30 μm, within 20 μm, within 10 μm, or within 1 μm of lying along the same plane. Two surfaces or components can be deemed to be “substantially perpendicular” if an angle therebetween is, for example, 90°±10°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°.
